[csswg-drafts] [cssom-view] scrollingElement quirksmode description looks wrong... a typo I think? (#5326)

deant has just created a new issue for https://github.com/w3c/csswg-drafts:

== [cssom-view] scrollingElement quirksmode description looks wrong... a typo I think? ==
In the description of what _scrollingElement_ returns when the document is in quirks mode, here:

[CSSOM View Module - scrollingelement](https://drafts.csswg.org/cssom-view/#dom-document-scrollingelement)

It states:

> If the HTML body element exists, and it is **not** potentially scrollable, return the HTML body element and abort these steps.

I think the "not" is incorrect, and should be removed...?
Surely it returns the element if it _is_ scrollable, and null otherwise, and not the other way around?
